Well the all the testing I have done in comparing the 2, a 550 2 pole actually puts LESS stress on the rest of the power system. From ESC temps, mAh being used and battery temps. Granted ALL my test were done INDOOR on HIGH GRIP CARPET track. While a 2 pole isnt ideal for most, its what works well for me. My testing yielded the results that a 4 pole motor generates MORE heat in the battery and ESC while using diving deeper into the overall mAh of the pack as well.

What I want to know is the actual torque values of a 2 pole 550 against a 4 pole 540.
I am not all that convinced that there will be much difference with reasonable punch settings. People can say what they want about power band, but the only thing that ever really matters is how much you lay to the ground. That being said, is there all that much difference in power vs the two?

Reliable dyno data is tough to get. I totally agree it is all about putting power to the ground. 550 2 pole will get it done. In certain conditions can even be better. Both can get you the winners circle. I like the lighter weight more than the extra torque.

Does anyone have a parts list to do the conversion? I have a practically NIB 2.0 that I built. Would prefer to not sell the truck!

On this topic, if you've got a 2.0 that already has the 22 shock conversion, -3MM chassis, dogbone center driveshafts, aluminum caster blocks and you don't plan to run the motor in the angled configuration, what's the difference besides the new front A-Arms?

I understand the 3.0 chassis is wider - how does that affect the performance of the car when not angling the motor?

The 3.0 chassis can allow for the angle changes on the center driveline and the battery configuration in front and back which is sort of an outdoor versus indoor thing. The chassis got wider due to the 550 motors being angled off the side cannot go outside of the chassis so we made room for those and thus we altered both sides equally and the chassis got wider much like the 8ight E 4.0 did.
